portaudio19-dev can't be installed without conflicts

[Daniel Schürmann]

Description: Ubuntu 14.04.2 LTS
Release: 14.04
Package: portaudio19-dev 19+svn20140130-1

We have some issues with portaudio and jack 1/2,
setting up a development environment.
A solution involves uninstalling the default libjack-jackd2-0

What you expected to happen:
Installing: portaudio19-dev should work without any issues on a stock install.

What happened instead:
The following packages have unmet dependencies:
 libjack-dev : Depends: libjack0 (= 1:0.121.3+20120418git75e3e20b-2.1ubuntu1) but it is not going to be installed

This was original reported for Mixxx (Bug #1326653)
The final build result (Mixxx) runs fine with libjack-jackd2-0
in place.

Reinstalling libjack-jackd2-dev after portaudio19-dev works.

libjack-dev is listed in the portaudio19-dev dependency.
I do not know how libjack-jackd2-dev can satisfy this dependency,
but this state should be somehow swapped.

Status changed to 'Confirmed' because the bug affects multiple users.

Any updates?
What can be done towards a solution?

same issue on ubuntu 16.04-2

if I install qjackctl:

The following packages will be REMOVED:
  libjack-dev libjack0 portaudio19-dev

PLEASE FIX

I'm afraid my terminal scrollback history isn't long enough for me to see the original error. Reinstalling libjack-jackd2-dev afterwards was not a possible solution due to the vast quantity of software it wished to remove!

I wish I knew exactly what I did but after installing all the other dependencies, apart from the jack libraries and it would remove half my system, running the build-dep command just worked without complaining about dependacies that aren't going to be installed and without trying to remove any other packages.

Looking around I did notice this, which seems to be a library for Port Audio using Jack2, which is what seems to be installed on most systems as far as I can tell.....

BUT I SOLVED IT by installing libjack-jackd2-dev first. After that, sudo apt install portaudio19-dev runs without trying to uninstall anything.
